The LoRaWAN module are compact, energy-saving LPWAN radio modules (Low-Power-Wide-Area-Network) that offer support for the LoRaWAN wireless protocol with a long range.
This new radio module is intended to help increase the worldwide launch of the LoRaWAN platform and make it a standard for LPWANs that support IOT applications with low power consumption.
The LPWAN module is the first to master two LPWAN technologies. Specifically, MOKOSmart was ported into the compact LoRaWAN module in addition to the existing LoRa stack. LoRa functions can thus be implemented worldwide on the same hardware basis. The concept leaves it to the customer to decide which network technology best meets the requirements of his application in terms of location, service requirements and costs.
LoRaWAN offer similar LPWAN capabilities (Low-Power Wide Area Network) and are suitable for smart meters, facility management, asset tracking and many other IoT applications. Although both network technologies have their specific characteristics, they are aimed at long range and high quality of service. Because the LoRaWAN module supports both techniques, it can also act as a bridge between them.If problems occur in a network, for example, applications can switch to the other protocol, so that redundancy is required for the communication connections.
It operates at frequencies from 806 to 930 MHz and achieves a nominal output power of +14 dBm, which can be increased to +20 dBm to increase the range and in applications with unfavorable signal propagation conditions.
LoRaWAN Module Characteristic
• Integrated TCXO with robust thermal properties with low drift offer a precise clock source for the RF transmitter-receiver
• An ADC and up to 18 GPIOs offer great flexibility for connecting sensors, switches and status LEDs
• Pre-certified radio regulatory approvals for operating 868 and 915 MHz in the industrial, scientific and medical (ISM) spectrum in most geographic regions of the world
• The module is operated with a supply voltage of 2.2 to 3.6 VDC
• The microcontroller contains 192 KB flash and 20 KB RAM
• The normal output power is +14 dBm, but a PA boost function can be selected to increase the RF output power to +20 dBm for long range applications
• Communication with the module can be achieved through UART, SPI or I2C peripheral interfaces
• The optional STSAFE fuse element can be integrated into the microcontroller to improve network security functions
• Operating temperature: -40 + 85 ° C
Application of LoRaWAN Module
• Intelligent electricity meters (Smart Meter)
• Portable devices
• M2M and Internet of Things (IoT) edge nodes
If you are looking for something on the Internet, you will very quickly find ready-made channels that send their data with LoRaWan and are just waiting for a gateway nearby to forward the data to a server. Here is a selection of links, which of course is never complete.
Long Range Wide Area Network (LoRaWAN)
Long Range Wide Area Network (LoRaWAN) is a low-power wireless network protocol that was specified by the LoRa Alliance. It is a free technology that uses a proprietary and patented transmission method. It is based on the chirp spread spectrum modulation technology called LoRa. LoRaWAN has been developed asymmetrically and with a focus on energy efficiency. In addition, the range is up to 10 kilometers with a transmission rate of 292 bits / s up to 50 kbit / s. At first glance, this appears to be very little for today’s conditions, but is completely sufficient for IoT devices for various applications.
A simple use case hacked – // park
Then a practical application for IoT Edge and LoRa WAN was presented using the simple use case “// Park”.
// Park – optimized parking space search thanks to IoT
// Park is a small project that we carried out within doubleSlash in Munich. It is used to research the technologies LoRa WAN and IoT Edge using a Rapberry Pis with LoRa module as LoRa gateway and a Seeeduino LoRa WAN as LoRa node.
In addition to exploring the two technologies, the parking situation at the Munich location was a main motivation for the // Park project. It should make the morning search for parking a little more pleasant for the employees of doubleSlash.
As can be seen in the figure, the worst case scenario for colleagues looking for a parking space in the morning consists of five steps:
1. Colleague is on the way to work
2. Colleague arrives at the double Slash branch
3. Colleague notes that all parking spaces in the underground car park and in the courtyard are full
4. Colleague must now look for another parking space. Dual mode operation is therefore possible on the basis of a uniform firmware package that can be used worldwide.
5. Colleague has a parking space and can now start his work
// Park now has the task of bridging step two and making life easier for colleagues. Because they save time and can start the working day more relaxed.
For this purpose // Park uses LoRa nodes with sensors as shown in the figure above to determine the current parking lot status and to make them available for further services in the Azure Cloud using a LoRa gateway and IoT Edge.
One of these services at // Park is the frontend, with which every employee can query the current parking status for any doubleSlash branch at any time via his smartphone or PC. So he can see at a glance whether it is worth driving directly to the branch for a parking space or whether it is better to strike at the next free parking space on the street.
End of the Azure DEV Meetup with networking and kicker
After the lecture, the participants and speakers exchanged experiences, suggestions and know-how on the topic of Azure. Of course, a round or two of kickers could not be missing. All in all, a successful evening and a good start to the new Meetup lecture series at doubleSlash.
Further information about Azure DEV Meetup Munich is available on LinkedIn, Twitter and of course also on the Meetup Portal. Become part of the Meetup Group and look forward to further interesting lectures and a good exchange.
Wireless M-BUS & LoRa Module
Compact SMD module with Lobaro wMBUS & LoRaWAN Multi Stack Firmware
Wireless M-Bus (wMBUS, Meter-Bus) is a widely used European standard (DIN EN 13757-4) in the field of smart metering. Many gas, water, electricity and heat meters can already be recorded with Wireless M-Bus and a wide variety of actuators can be controlled. The type of sensor to be queried is not restricted and Wireless M-Bus is used, among other things. also used for humidity / temperature sensors, pulse converters, analogue-digital converters.
Thanks to the special Lobaro firmware, we can offer you an energy-saving wireless module, especially for the above-mentioned. Offer application scenarios in (sub) metering. We integrate this into your application scenario in the shortest possible time. Standard applications include the reception of wMBUS telegrams and the subsequent transmission via a LoRaWAN network. Uploading via cellular networks (2G, LTE, NB-IoT) is also no problem with the LOB900C & a GSM modem!
The module has a powerful 32-bit Cortex-M3 processor in combination with the Semtech SX1272 radio transceiver, which can be used to implement customer-specific firmware solutions thanks to the Lobaro multi-stack firmware.
